Which renowned resolution was adopted by the Indian National Congress under Gandhi's leadership in 1929? 

a) Lucknow Session Resolution 

b) Quit India Resolution 

c) Lahore Session Resolution

The correct answer is c) Lahore Session Resolution.

This resolution, adopted by the Indian National Congress in December 1929, was a landmark moment in India's freedom struggle.

The Call for Purna Swaraj (Complete Independence)

The Lahore Session of the Indian National Congress was presided over by Jawaharlal Nehru. While Mahatma Gandhi was the guiding force of the movement, Nehru led this pivotal session.

The key outcome was the Purna Swaraj resolution, which officially changed the goal of the Congress from seeking Dominion Status within the British Empire to demanding complete independence from British rule.

Following this historic declaration:

• The newly adopted tricolor flag was hoisted by Nehru on the banks of the Ravi river on December 31, 1929.
• The Congress declared January 26, 1930, as "Independence Day," a date celebrated for years until India gained actual independence. Later, to honor this date, January 26th was chosen as India's Republic Day.

Why the Other Options are Incorrect

• Lucknow Session Resolution (1916): This session is famous for the Lucknow Pact, which fostered unity between the Congress and the Muslim League, long before 1929.
• Quit India Resolution (1942): This resolution, which called for the British to "Quit India," was passed much later, on August 8, 1942, during World War II.
